Definitions

  • This invention relates to an automatic paper feed device which supplies cutforms and other media automatically to terminal devices such as printers.
  • a device to automatically supply media to terminal devices such as printers was disclosed in Japanese Patent Application Laid-open No.218238/1985.
  • terminal devices such as printers
  • Media are stored in and supplied from these hoppers.
  • Figure 1 is a partially cut-away side view showing the conventional paper feed device.
  • Media 2 is stacked and stored in hopper or cassette 3, which is installed in automatic paper feed device 1.
  • Printer 4 is placed on top of automatic paper feed device 1.
  • Supply roller 5 is installed above cassette 3 and feed roller 6 is also disposed inside the device.
  • spring 7 is provided underneath media 2.
  • Cassette container 9 is installed to the side of automatic paper feed device 1 and printer 4.
  • Cassette container 9 contains cassettes 8 which store specific sizes of media which are not in use.
  • the operation of the conventional automatic paper feed device will be explained next.
  • the media 2 which is stacked and stored in cassette 3 is pushed by spring 7 into contact with supply roller 5.
  • Supply roller 5 is rotated in the direction of arrow G by a drive means not shown, and this causes the media to begin to be fed from the top, one sheet at a time.
  • Media 2, which has begun to be fed, is sent to printer 4 by feed roller 6.
  • cassette 3 When one wishes to print media which is different in size from media 2 (stacked and stored in cassette 3) with printer 4, one takes cassette 3 out of automatic paper feed device 1.
  • Cassette 8 in which is stored the media of the size desired, is then taken out of cassette container 9 and installed in automatic paper feed device 1. Paper feed to printer 4 may then be performed.
  • Cassette 3, which has been taken out of automatic paper feed device 1 is then stored in cassette container 9. By manual input instructions are sent to printer 4 concerning the size of the media newly installed in automatic paper feed device 1.
  • cassettes for respective sizes of media are necessary in devices constructed as above. Also, since the automatic paper feed device permits mounting of only one cassette a separate place or container for the multiple cassettes storing media not in use are needed. Because of this, cassettes not being used must be placed in the immediate vicinity of the automatic paper feed device and the amount of space needed for the installation of the device is a problem.
  • the automatic paper feed device described above also has the fault of requiring a number of cassettes in which specific sizes of media are stored. Because of this cassette container must be provided and this increases the number of structural parts, and raises the price of the automatic paper feed device.
  • a single paper cassette suitable for different sizes of paper is disclosed in the document DE-A-33 31 077. It comprises a media load plate positioning the paper by a back edge guide assembly, which is in particular capable for obtaining the paper size and providing electrical signals according to the paper size.
  • DE-A-24 16 782 is concerned with a paper cassette comprising in particular a turnable paper load plate and some guide members.
  • An object of this invention is to solve the problems described above, making it possible for the installation area to be smaller and providing an inexpensive automatic paper feed device of excellent operability.
  • the paper cassette is first pulled outside of the body of the automatic paper feed device.
  • the media load plate inside the paper cassette is rotated to a specified direction and lowered.
  • the maintaining means which maintains the position of the detection lever, is released.
  • the media is stored on the media load plate and the media back edge guide assembly is moved in response to the size of the media.
  • the media back edge guide assembly is stopped at a position corresponding to the size of the media, and the media is positioned.
  • the detection lever which is engaged with the media back edge guide assembly by the engaging means, is rotated to accompany its movement. In the above-mentioned position to which it was rotated the detection lever operates the detection means and detects the size of the media.

  • hopper 12 In order to set media, hopper 12 must be pulled out of device 11. In preparation therefor, shaft 30 is rotated in the direction E by lever, not shown. Then media load plate 17 is lowered by rotation in the direction F, via reset arm 31, shaft 29 and flanges 27a, 27b. At this time, separation claims 22a, 22b fall, due to gravity, rotating about pivot axis 23, until the upper extermities of slits 25a, 25b abut protrusions 26a, 26b of guide block 24a, 24b. In this state, hopper 12 can be pulled out of device in the direction A without interference between hopping roller 14 and media load plate 17, or separation claws 22a, 22b.

They then slide on the side face of guide bracket 35 and fit into slits 36a and 36b, which correspond to the length of media 2. Media back edge guide assembly 44 is stopped in this position. Because a bias force is applied to convex sections 42a and 42b of plate spring 41 media back edge guide assembly 44 is stopped and held in the position in which they have been inserted into slits 36a and 36b. This positions media 2 in the delivery direction.
  • media back edge guide assembly 44 Along with the movement of media back edge guide assembly 44, detection lever 46 rotates with fulcrum 47 as its center from the position shown by the solid lines in Figure 6 to the position shown by the phantom lines. This rotation accompanies the movement of media back edge guide assembly 44. At this point media 2 is set on media load plate 17. Because the distance between the top of media load plate 17 and guide plate 43 is equivalent to the length of one side of media 2, the media is positioned in such a way that it will not slip. In this state, the front of media 2 is in abutment with guide blocks 24a and 24b.
  • Detection lever 61 is formed of a resilient material. It is attached to bottom plate 21 of hopper 12 in such a way that it is able to rotate freely on fulcrum 47. Pilot pin 48 is provided on one end of it, on the other is provided flat section 49. Convex section 62, which juts out to the side of bottom plate 21 of hopper 12, is also formed on detection lever 61. Apertures 63 and 64 are formed on the same circle on bottom plate 21 of cassette 12 as convex section 62, which has fulcrum 47 as its center.

  • Detection lever 71 is formed of a magnetic material. It is attached to bottom plate 21 of cassette 12 in such a way that it is able to rotate freely with fulcrum 47 as center. Also, a number of magnets 72 and 73 are disposed at positions on bottom plate 21 of cassette 12 corresponding to the sizes of media. Because other aspects of its structure and operation are the same as the second embodiment their explanation will be foregone.
